Important Information

CAUTION: USE OF THE POLARIS IN A VINYL LINER POOL

Certain vinyl liner patterns are particularly susceptible to rapid surface wear or pattern removal caused by objects coming into contact

with the vinyl surface, including pool brushes, pool toys, oats, fountains, chlorine dispensers, and automatic pool cleaners. Some

vinyl liner patterns can be seriously scratched or abraded simply by rubbing the surface with a pool brush. Ink from the pattern can

also rub off during the installation process or when it comes into contact with objects in the pool. Zodiac Pool Systems, Inc. is not

responsible for, and the Limited Warranty does not cover, pattern removal, abrasion or markings on vinyl liners.

• Before installing the cleaner, make sure the pool filter is clean.

• New plumbing lines should be flushed out before installing the cleaner.

• The Polaris should not be used to remove plaster dust in new pools.

• Disconnect the cleaner before cleaning or backwashing the pool filter. After cleaning, let the

filtration system run for at least five (5) minutes before re-connecting the cleaner.

• Always remove the Polaris from the pool before super oxidation or chlorination treatments.

WARNING

To avoid risk of injury, do not handle the Polaris while it is operating, except when checking the

wheel RPM. Always remove the cleaner before swimmers enter the pool.

Congratulations on the purchase of your new automatic pool cleaner, and thank you for

choosing Polaris. The Polaris 3900 Sport/P39 is designed to give you years of dependable

and efficient service.

Like most mechanical devices, it will require periodic adjustments, routine maintenance, and

the replacement of certain hardworking parts. Please have the cleaner checked occasionally

by your local Polaris dealer or service center.

Always insist on genuine Polaris replacement parts. Non-Polaris parts are not made to our

specifications. They may have an adverse effect on the operation of your Polaris or may even

damage it.

For best results, the cleaner should be installed by a pool professional. For those with

experience and confidence in handling plumbing and mechanical equipment, installation is

outlined in this manual.

Install the Universal Wall Fitting

1. Turn on the filtration pump and flush out the plumbing line.Turn pump off.

2. Remove the Universal Wall Fitting (UWF

®

) from the Quick Disconnect and screw it

into the return opening with the blue restrictor disk in place.

3. Turn the Quick Disconnect clockwise into the UWF and pull away to secure. The Quick

Disconnect will click into place.

Adjust Feed Hose To Fit Pool Length

1. Measure the deepest part of the pool. Cut leader hose from the end that attaches to the

feed hose (away from the back up valve) so length is equal to the greatest depth of the

pool.

2. Attach leader hose to feed hose and connect hose to the pool wall at the return line.

Extend hose to farthest point of pool. The hose end must be within 6 inches – longer or

shorter – of the farthest point. See diagram below.

If hose is too long: Separate hose at center swivel. Cut half of the overage from each

10-foot feed hose section that attaches to the center swivel.

If hose is too short: Add a feed hose section (part #9-100-3104), a swivel (part #D20)

and two (2) hose nuts (part #D15). Adjust to proper length.

Each feed hose section should be equal in length after adjustments.

3. After adjusting the length, position the hose floats as shown.

CAUTION

Use caution when cutting the hose to prevent injury inflicted by the cutting tool.

3. Turn on the pool filtration

pump and allow it to prime

before turning on the booster

pump. (Refer to booster pump

manufacturer’s instructions for

booster pump priming time.)

Check for Proper RPM

Before operating the Polaris, check

for proper wheel revolutions per

minute (RPM).

For maximum efficiency, the cleaner

should operate between 30 and 36

RPM.

1. Mark the single-wheel

side tire.

2. Turn pump on, hold cleaner

below water level and count

wheel revolutions for one minute.

If count is not in target range,

refer to Adjusting the Wheel

RPM in the Troubleshooting

section for more information.

Cleaning the Bag

Empty the filter bag when it is

half full, especially if the debris

load is sand.

It is easier to empty the filter

bag when it is dry. Alternate

between two (2) bags.

To remove the bag, detach the velcro

strips. Twist the bag collar and pull up to

free the bag from the cleaner. Unzip both

sides of the bag to remove the debris.

Routine Maintenance

Fine Tuning The Cleaner

When operating correctly, the cleaner vacuums, sweeps and scrubs all surfaces randomly

throughout the pool. Approximately every three (3) minutes the cleaner goes into back-up mode.

This action pulls the cleaner away from pool obstacles and increases its random pattern.

Thrust Jet Adjustment

The thrust jet powers the direction of

the cleaner. Factory position is seven

(7) o’clock but, depending on the

pool, other settings can be helpful to

improve cleaner coverage.

Sweep Hose Adjustment

The sweep hose should move in a

gentle sweeping motion. To adjust

the motion, turn off the booster pump

and turn the sweep jet clockwise

to increase or counter-clockwise to

decrease the movement.

Cleaning the In-Line Filter

Screen

To clean the in-line filter screen, pull it out

of the filter assembly, rinse and press firmly

back into place.

Storage and Winterizing

Never store the cleaner in direct sunlight. When storing for the winter, drain all the water from the

cleaner (freeze damage is not covered under the warranty). Use the Quick Disconnect to remove

the UWF from the pool wall. If necessary, use the UWF Removal Tool (part #10-102-00) available

from any Polaris dealer.

CAUTION

Always disconnect the Polaris before cleaning or backwashing your pool filter to avoid potential

clogging or damage to the system. Allow the filtration system run for at least five (5) minutes

before re-connecting the cleaner.

If the cleaner regularly displays any of the following

actions, adjustments may be necessary to restore

performance. Refer to the exploded parts diagram

for part references.

Action: Cleaner hangs up on steps or other

obstacles for longer

than 3 minutes.

Solution: 1. Check the wheel RPM.

2. Verify the back-up valve is cycling.

Lift the valve out of the water and

watch the jet. It should come on and

go off.

3. Adjust the thrust jet.

4. Remove unnecessary pool hardware

or install a Ladder Guard Kit (part

#G21).

Action: Cleaner is sluggish, running with less

power than normal.

Solution: 1. Check the filter screen in the

in-line filter assembly and clean

if necessary.

2. Clean the skimmer basket, pump

basket, and pool filter.

3. Check the hoses, hose connections,

and swivels for leaks that could cause

loss of water pressure.

4. Check the wheel RPM. If

below 30 RPM, see Adjusting the

Wheel RPM to increase flow to

cleaner.

Action: Cleaner races around the pool and/or

does not make contact with the pool

bottom.

Solution: 1. Check the wheel RPM. If

more than 36 RPM, see Adjusting

the Wheel RPM

to reduce flow.

2. Verify the back-up valve is cycling.

Lift the valve out of the water and

watch the jet. It should come on and

go off.

Troubleshooting

Action: Cleaner doesn’t back up.

Solution: 1. Verify the back-up valve

is cycling. Lift the valve out of the

water and watch the jet.

It should come on and go off.

2. Check the wheel RPM.

If not in 30-36 RPM range, see

Adjusting the Wheel RPM.

3. If the filter bag is full, empty

or replace it.

4. Make sure feed hose

is floating.

Action: Cleaner only turns in one direction.

Solution: 1. Adjust the thrust jet.

2. Make sure feed hose

is floating.

Action: Feed hose becomes tangled.

Solution: 1. Remeasure the hose to verify that it is

adjusted to the proper length for the

pool.

2. With the cleaner operating, check that

the swivels and

hose connections turn freely.

3. Make sure the feed hose

is floating.

4. With the Polaris operating,

hold the cleaner under water and

verify that all three (3) wheels are

turning together.

Action: The front end of the cleaner

lifts all the time.

Solution: 1. Check the wheel RPM.

If not in 30-36 RPM range, see

Adjusting the Wheel RPM.

2. Adjust the thrust jet

downward.

3. Verify the back-up valve is cycling.

Lift the valve out of

the water and watch the jet.

It should come on and go off.

4. Check for water inside the cleaner

float.

Page 10

English

Action: Sweep hose is sucked into the

vacuum tube.

Solution: 1. Make sure the opening at the end

of the sweep hose is not blocked by

the sweep hose scrubber. Replace

scrubber if it is worn or missing.

2. Adjust the sweep hose to a gentle

sweeping motion.

3. Check the wheel RPM. If

more than 36 RPM, see Adjusting

the Wheel RPM to reduce flow.

4. Add a sweep hose weight

(part #B2).

Action: The cleaner does not clean the

entire pool.

Solution: 1. Verify that feed hose reaches within

6 inches of the farthest point of the

pool. If not, order a new hose section

from your Polaris dealer.

2. Adjust thrust jet to improve coverage.

Action: The cleaner is running in circles on

its side.

Solution: 1. Check for water inside the cleaner

float.

2. Check the filter bag, if full it can weigh

the cleaner down on one side.

3. Check the hose floats to make sure

they are spaced evenly.

4. Check the wheel RPM. If

more than 36 RPM, see Adjusting

the Wheel RPM to reduce flow.

Adjusting the Wheel RPM

If count is less than 30 RPM:

• If an adjustable valve is installed on the

cleaner line, open it completely so water can

flow freely to the Polaris.

• Check the filter screen in the in-line filter for

debris that restricts water flow.

• Clean the skimmer, filter and pump basket,

clearing debris that restricts

water flow.

• Check the hoses, connections and

swivels for leaks that cause loss of

water pressure.

• Remove the blue restrictor disk from

the UWF

®

.

If count is more than 36 RPM:

• Replace the blue restrictor disk in the UWF

with the red restrictor. If the flow is still too

high, unscrew the pressure relief valve until

the proper RPM is reached.

NOTE The pressure relief valve should only be

adjusted when a restrictor is installed.

• If an adjustable valve is installed on the

cleaner line, adjust it to reduce the water

flow to the cleaner.
